Domingo Garcia, national president of the Latinx advocacy group, told reporters during a Wednesday press conference that it's raising boosting its cash offer for information that leads to the woman to $10,000 from $5,000.
Earlier this week, the New York Times identified the mystery woman as San Antonio native Perla Huerta, a former army medic. Although the Bexar County Sheriff's Office hasn't confirmed Huerta as a suspect, sources familiar with the investigation told the Express-News she is a person of interest.
In addition to boosting its reward, LULAC on Wednesday filed a complaint with the Department of Justice, demanding that Attorney General Merrick Garland open a criminal investigation into Huerta along with Florida Gov. DeSantis and Texas Gov. Greg Abbott.
LULAC also set up a tip line — (818) 689-9991 — for people to provide information on Huerta.
"It's time Perla Huerta goes before a grand jury and answers who hired her, who paid her and what was her purpose of her mission," Garcia said at the press conference.
Last month, Bexar County Sheriff Javier Salazar launched an investigation into the Martha's Vineyard flights, which were arranged by DeSantis. Salazar said the migrants were lured onto the planes under "false pretenses" that may have broken the law. Some of the stranded migrants told reporters they were promised jobs and lodging.
DeSantis reportedly arranged the flights after making contact with Texas' Abbott, a fellow Republican. Abbott has made anti-immigrant rhetoric a key part of his reelection campaign and chartered numerous buses to ship migrants out of the state.
Garcia said a federal investigation into the flights is necessary, adding that the "political stunt" misused Florida taxpayer money, involved human trafficking and violated several immigration laws.
According to an investigation by Express-News, Perla's last known residence was a condo in Tampa.
"Texas Governors Greg Abbott and Florida Governors Ron DeSantis are the real shot callers in this disgusting exploitation of innocent human beings," Garcia said in a statement. "LULAC urges the U.S. Department of Justice to conduct a rigorous and transparent investigation into these elected officials' potential civil and criminal violations."
